2-D FIR Filters, Linear Prediction and 2-D IIR Filters

The technical field of image processing began during the latter half of the nineteenth century in the early days of chemical photography. Image processing then branched into the evolving fields of radio wave transmission and X-ray technology during the early twentieth century. Based on this evolutionary trend image processing became highly interdisciplinary during the twentieth century and has continued to quickly move forward during the twenty-first century. 2-D FIR filters are widely used image processing because the feasibility of generating zero-phase or linear phase characteristics controls phase distortion because of the importance of phase in image processing.
